Recommendation: Monitor — no exploitation signal at the moment.

The Goobi viewer is a web application that allows digitised material to be displayed in a web browser. From 4.8.0 to before 26.04.1, the Goobi viewer REST endpoint POST /api/v1/index/stream accepted an arbitrary Solr streaming expression from unauthenticated network clients and forwarded it to the backend Solr server without restriction. An attacker could read the complete Solr index and, in default Solr deployments, also modify or delete indexed records. This vulnerability is fixed in 26.04.1.
